3 videos eating the same species in the wild all the same moray involved yellow margin Gymnothorax flavimarginatus seems to specialize in eating other moray? I can't find any info on this moray which also the most beautiful of them all I think. There is nothing written about them or feeding habbits. Usually moray are okay together well at least in captivity.

There is info about them out there, you're just not looking hard enough, I read they're similar to green morays getting only slightly smaller and being real aggressive and should be kept alone. I can't get real specific as this was a number of years ago when I was curious about it after seeing the 4'+ one at my lfs. Definitely a beautiful fish, I'm sure there's more info out there now than there was back then. Might wanna check the saltwater section since it's a saltwater fish...
